T 0 LZZ whom t may concern:

Beit known that I, ARCHIBALDPUNTENEY, of Kansas City, Jackson county,Missouri, have invented certain new and useful Improvements inSweep-Rakes, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart thereof.

My invention relates to rakes, and more particularly to improvements inthat class known as sweep-lakes, and the object of the invention is togenerally improve the mechanism for raising or lowering` the rake.

A still further object of the invention is to produce a rake embodyingthese improvements which is of light draft and st-rong, durable, andcomparatively inexpensive of manufacture.

To these ends the invention consists in certain novel and peculiarfeatures of construction and arrangement, as hereinafter described andclaimed.

In order that the invention may be fully understood, reference is to behad to the accompanying drawings, in which Figure 1 represents inperspective a sweeprake constructed in accordance with my invention.Fig. 2 represents, on a larger scale, a side elevation of the same. Fig.3 represents in section the upper end of the casterwheel standard andshows the same ernbraced by one half or one section of the coup- -lingblock or casting, and shows also a bearing-pin journaled loosely insaid' standard and said coupling-section. Fig. 4 represents a verticalsection of the coupling-block and of the pin, taken at right angles tothe section shown in Fig. 35and Fig. 5 is a horizontal section taken onthe'line x 5c of Fig. 3, these three figures being shown on a muchlarger scale in Figs. 1 and 2.

In the said drawings, 1 designates a transverse bar, to the under sideof which the rear ends of a number of rake-teeth 2 are bolted, saidrake-teeth being arranged parallel with each other and at right anglesto the bar 1. A suitable distance forward of and parallel with the bar 1is a second transverse bar 3, which is bolted to the under side of saidteeth.

4C designates bars which are bolted to the opposite ends of the bar 1and project outward and very slightly to the rear, preferably, and 5designates draft-bars or tongues l29, secured to the longitudinal bar12.

which diverge slightly to the front and are secured upon bars 4f bybolts G, which bolts serve also as a means of securing together the bars1 and 4 and the end teeth of the rake. Said tongues or draft-bars 5 arebraced from outward movement by means of the rods 7, which connect themwith'the bars 4.

3 designates clips which are pivoted to the outer ends of the bars f1and are coupled loosely to the singletrees 9 in the customary manner. Tothese singletrees the draft-animals are hitched in the usual manner.

l0 designates bars which are bolted rigidly to the under side of therake-frame and centrally thereof and converge at equal angles to therear, where they are united by parallel cross-beams 1l, and bolted inturn to the upper side of said cross-beams and centrally thereof is thelongitudinal bar 12, upon the rear end of which is secured a reinforcingmetallic sleeve 13, provided with an upwardlyprojecting boss or lug 14,in which is loosely journaled the vertical cylindrical standard 15 ofthe caster-wheel 16.

17 designates a casting or metallic coupling whiehris cylindrical inform and comprises two similar halves or sections, from the rear upperends oil which project the lugs 18 and from the front lower ends thesimilar lugs 19. The sections are secured together by bolts 20 and 21,which extend through the lugs 1S and 19. formed with a semicylindricalcavity, which co'njointly form the cylindrical hole or opening 22, inwhich the upper end of the casterstandard 15 is loosely journaled, andsaid sections are also provided with semicircular grooves or channels,which together form the single circular groove or channel 23, into whichthe opposite end of the hardenedsteel pin 24 loosely projects, said pinbeing loosely journaled also in the opening 25 of' said standard, asshown clearly in Figs. 3, 4, and 5.

2G designates a short link which is pivotally mounted at its rear endupon the bolt 21 and is pivotally bolted at its opposite end to oneendof the lever 27 ,which leveris pivotally connected to the upper endof a swinging link 2S, pivotally mounted in turn upon the bolt jacent tosaid lever and bolted rigidly upon the bar 12 is the frame 30, providedwith the notches 3l and 32 for engagement at times IOO with the lever27, which lever, it may be observed, is preferably of spring metal, sothat when it is thrown into one of said notches it will hold suchposition until the Operator disconnects it, as will be readilyunderstood.

Bolted to the end rack-bars above the bar 3 are standards 33, and saidstandards brace and are braced in turn by the tongues or draft-bars 5,to which they are bolted. Said standards 33 provide a support for aswingin g hay-discharge frame which is constructed as follows: 34designates a transverse bar which is pivotally connected at its oppositeends to the upper ends of said standards, and 35 a number of dependingteeth which are secured at their upper ends to said bar. 36 designates ahandle, which is bolted also to said bar near its middle, whereby saidhay-discharge frame may be pivotally operated. Depending` from the rakea suitable distance from its rear end are the bearing-blocks 37, inwhich are secured the axles 38 of the supporting-wheels 3?),and saidsupporting-wheels are inclosed at their upper sides by the guards 40, soas to prevent the hay being caught and entangled with the said wheel.The drivers seat il is arranged within convenient distance of the levers27 and 3G and is supported in the customary manner by a standard of theframework.

In the practical operation of the machine as it is drawn across thefield the lever 27 is in engagement with the notch In moving to suchposition, because the rear end of the lever is fulcrumed to the link2li, carried by the substantially-fixed coupling 17, the link 28,together with the rear end of the machine, is lifted until thebearing-lug 14 is adjacent to the lower side of said coupling, and thefront end of the rake, which tilts upon the front wheels, is depressedto the position indicated by the head of the arrow a. Occupying thisdownwardly and forwardly inclined position, it is obvious that in thetravel of the machine the hay encountered is caused to roll or pile uponthe rake, and each fresh charge of hay gathered by the rake forces thatalready accumulated farther to the rear, until finally, when the machineis fully loaded, the hay is packed thereon to the rear as well asforward of the axis of the wheels, so that the load is practicallybalanced upon the machine. As it accumulates in such quantity upon therake its natural tendency is to move rearward and over the rear end ofthe same, but this is prevented by the swinging frame hereinbeforedescribed. Vhen a sufficient quantity of hay is gathered upon the rake,the driver grasps the lever 27, disengages it from the notch 32, andforces it forward into engagement with the notch 3l, thereby loweringthe rear end of the machine to the position shown in Figs. l and 2 andraising the front end of the rake until the teeth 2 occupy a horizontalplane. The driver needs to exert himself only slightly in thisoperation, because of the fact of a part of the load being rearward ofthe axis of the front wheels, which form the pivot or balancing point ofthe rake, and it is evident that the draft-animals are also relieved ina considerable degree. When the stack is reached, the lever is againthrown rearward to its original position, so as to tilt the front end ofthe rake downwardly, andthe machine is trailed rearwardly, and at thesame time the swinging frame is moved in the direction indicated by thearrow, Fig. 2, so as to accelerate the discharge of the hay from therake, which saves considerable time and inconvenience in that it isdelivered at the precise point desired. The hinged frame being locatedand arranged as described prevents hay from falling over the rake whenfully loaded and when traveling to the stack, and as a result cleanerand better work is done.

As a means both for relieving the draftanimals of considerable work andof increasing` the durability of the machine I have provided theconnection between the operatinglever and the caster-standardillustrated clearly in Figs. 3, 4, and 5. The method of securing saidcoupling and said standard together provides a simple, strong, anddurable, and yet practically an antifriction connection between thecoupling and standard, and the pin 24, which bears most of the work andstrain at this point, is mounted loosely in the standard and groove ofthe coupling.

From the above description itis obvious that I have produced asweep-rake which will be found of great service and by which the workmay be expedited and the draftanimals relieved in a considerable degree.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, in a sweep-rake, of asuitable frame mounted uponwheels, rearwardlyconverging bars secured to said frame, transverse barsconnecting the rear ends of said converging bars, a short longitudinalbar secured upon the transverse bars, a notched or rack frame secured tosaid bar, a bearingboss also secured to the same, a caster-carryingstandard journaled in the said boss, a cross-pin carried at its-uppercnd,a cylindrical coupling mounted upon the upper end of saidcaster-carrying standard, and provided with an annular horizontal grooveengaged by the projecting ends of said cross-pin, a link pivoted to saidcoupling, a lever pivoted at its lower end to said link, and adapted toengage said rack-bar, and a link uniting said lever outward of itspivotal point with the said longitudinal bar, substantially asdescribed.

In testimony whereof I afiix my signature in presence of two witnesses.
